To all whom it may concern:

Be it known that I, JOHN Km, residing at Saville House, Shadwell, Leeds, in the county of York, England, have inventednew anduseful improvements in or relating to.

pedestals for supporting shafting and other rotating portions of machinery, and

meansfor lubricating the same, (for which I have'filed an application in Great Britain.

and Ireland, Serial No. 120,006, filed June 1, 1918,) of which the followingisa'specification. I i

This inventionhasreferenceto mprovements in that type of pedestals, -preferably called paddle lubricating pedestals,em-

ployed forsupporting shafting and for rotating portions ofmachinery ofthe klnd n which the lubricant, say oil, is raised by a collar, and in which meansare also provided for preventing waste of the lubricant. 5

' The object of this invention is to provide a pedestal or hearing for supporting shafting without the use of one ormore bushes, the shaft being supported by means of antifrictional rollers working 1n grooves formed in a sleeve fixed upon the shaft, the periphcries of the said rollers being varranged to work upon the peripheriesof the circular recesses formed in the pieces or partition walls whichdivide the pedestal and its cap into three cavities orv compartments; communication between the said compartments and the bearing surfaces of'the circular recesses being by means of horizontal and vertical passages. I In this invention the lubricant is caused to be raised and to circulate on to the said bearing portions by the sleeve without any additional special arrangement of rollers or scrapers or lifting devices, such as scoops or the like, and to be returned from the collecting compartments to the well or tank portion of the pedestal instead of passing along the shaft or down the outside of the pedestal and be wasted. a

1; Like partsyin-v all the' views are marked with similar letters of reference.

a and b are respectively the pedestal 'an db its cap which are of ordinary construction, externally but provided with an internal cavity which isformed in three compartr ments 0, 0 0' of different sizes, the two outer compartments 0 0 being narrower in width ,than the central compartment -0. j Each; of the compartments is formed in the cap as well as in the main portion or body of the p'edestal, and they are shaped as shown at Figs; 1

1 to 4:. I The compartments are divided by the rdlVlSlOIl pieces 0 c which areof such a width as to form a bearing surface upon which the hereinafter. described antifrictional rollers 7' work. Circular. openings 0 c areprovided in the division .pieces .0 0?

and a communication is formed-between the compartments 0- 0? with the centralxcompartment c by means of the horizontal pas- 7 sages 0 0 formed respectively within the division pieces 0 and a. In order to lubri ,cate the anti-frictional rollersj vertical passages c 0 are formed in the division pieces 0 c and the said vertical passages communicate: at their lower ends with theihorizontal passages or", 0

The cap I) is retained I thatifor large shafts it may be made'in anynumber of parts, each portion being pro vided with a lug so that the parts can be securedftogetherand the portions of the said sleeve fixed or clamped upon thefshaft. The, major portion of the sleeve f rotates in the central portion 00f the cavity. Inthe sleeve f are cut, when required, two circumferential V grooves i, i in which are inserted anumber'of antifrictional rollers j, j, shown more particularly at Figs. 6 and 8. Thediameter of the-sleeve in the portions where the circumferential grooves i,?l are cut is less in size than thehereinbefore mentioned circular holes formedin the division pieces 0 0 so as to provide for the peripheries of the anti-frictional rollers j being S in contact With, and working upon, the inner peripheries of the said holes in the division pie'ces.

The holes (1 a inthe outer portionsa, b of the pedestals are larger in diameter than the shaft 6. The central hole in the sleeve k is made of such a diameter'that the sleeve when clamped upon the shaft will be held tightly thereon. v

The action of lows t Oil-or other lubricant is placed "in the compartment 0, c 0 to the required hei ht, say, to any suitable level below the sha t e, andbymeans of the passages 0 c, 0 0 the oilwill circulate from one compartmentto the apparatus is as folthe other and also to the circumferential grooves z and anti-frictional rollers j placed ftherein. 'As the Shaft revolves the lugs f on the sleeve f form agitators for agitating the oil and for lifting it up on to the outer peripheryof the sleeve and for lubricating the rollers and bearing portions of the sleeve. At the same time by arranging the smaller compartments 0 0 beyond the ends of the sleeve provisionis made for collecting the 011 in the pedestals and for preventing it from passing through the circular openings a}, a in the pedestal itself; the passages c and 0 permit of the oil or other lubricant to return to the larger and central compartment 0, thus saving the waste of oilthat frequently takes place when an on dinary and constant dripping lubricator is employed.

'By constructing pedestals as herein described with the central cavities, the use of brass and other bushes is avoided, and provision is made by providing the sleeve with the central recesses and allowing the antifrictional rollers j to rotate in the circular construction'and also mounted upon sup porting frames as welLas. for use upon machines or frames where ordinary pedestals are employed. V 5 1 "What I claim is:-' V I 1. A pedestalfor supporting shafts and other parts of maehineryyhaving a main portion divided into three compartments, a cap for the said main port-ion'provided with a 7 corresponding number of compartments, the

said compartments in both the main portion and the cap being of different sizesythe division pieces-which separate the-[compartments being of a width to' form' bearing surfaces, and having circular openings and horizontal vertical communication passages, formed therein, anti-frictional rollers mounted 'on said beari'ng surface which support-the I rotating shaft, said 1 shaft having a sleeve made inp'arts fixed thereon and provided with lugs, asset "forth. 2. In a pedestalfor supporting shafting the combination ofa main portion and a cap,

each divided into three compartments therein and having circular openings and horizontal and vertical" communication passages formed in the division pieces between the comp artments, anti-frictional rollers for supporting the shaft arranged to workin said circular openings, a shaft mounted upon said rollers, a sleeve mounted upon the shaft and made in a number of-parts' and provided with lugs by'which the parts arebolted together,-

the sleeve having circumferential grooves formed in the periphery of'the; sleeve for the reception of the anti-frictional rollers," as and for the purposes set forth.

8. In a shaft support, the combination of a pedestal comprising a base'portion, di-

vided into three compartments by parallel partitions,anda cap portion, a sleeve adapted to be clamped about ashaft and provided with two circumferential grooves adapted" tofregister with the partitions in the'said base, and a series'of antifriction rollers arranged ine'ach said groove and bearing upon said partitions, for the purposedescribed;

4. In a shaft support, the combination'of a pedestal comprising a base portion, divided into three compartments by parallel partitions, and a cap portion, each of said partitions having passages formed therethrough for connecting the several compartments and lubricant duets extending from said passages to the upper faces of the par- 7 titions, a sleeve adapted to be clamped about a shaft and provided with two circumferential grooves adapted to register with the partitions in the said base, and a series of antifrictional rollers arranged in each said groove and bearing upon said partitions, for 10 the purpose described.
